Sir Gavin Williamson has resigned from his ministerial position after accusations of bullying.
His resignation letter came shortly after a former civil servant, who claimed Sir Gavin told them to "slit your throat", made a formal complaint against him.
In his resignation letter, Sir Gavin Williamson told Rishi Sunak: "As you know, there is an ongoing complaints process concerning text messages I sent to a colleague. I am complying with this process and I have apologised to the recipient for those messages.
